I had purchased thru Rail Europe website & get my Swiss travel 8 day pass e-ticket last month for 4pax. This is 2nd visit to Swiss. Unknown that the e-ticket printed with passport no. as previously I written on the hard copy.

Now I just renewed my passport, how shall I do & what is the cost ?

I wrote to Rail Europe, they reply may have to cancel & rebook, refund will subject for 15% cancellation charges if trainer operator can't waive off.Then I wrote to SBB ticketshop, they reply ticket alteration will charge CHF10 but I am not purchase from SBB.

The standard procedure for most if not all retailers is to cancel the old pass (85% refund) and then get a new one. I don't think the SBB ticket shop would change a pass for CHF 10. That sounds like the fee for changing a regular point to point ticket, but I might be wrong.
